(Cl. 131-198) This invention relates to a smoking article for smoking cigarettes, cigars and pipe tobacco, and more particularly to the construction of the mouthpiece thereof, which smoking article eliminates or reduces the dangers of inhaling toxic substances contained in tobacco smoke, and which article dilutes and cools the tobacco smoke drawn through the mouthpiece.

Cigarette holders, cigar holders and tobacco smoking pipes heretofore available have attempted to reduce the harmful effects of the toxic substances in tobacco smoke by obstructing to a certain extent the inhalation by the smoker of the tars, etc. by placing filters, such as cotton, wool, solid porous materials, etc. in the stem of the smoking article.

In the present invention an entirely different principle is utilized to remove the harmul substances in the smoke. Thereis provided a separate channel for the inhalation of tobacco smoke and a separate channel for a proportionate (15-20%) amount of free atmospheric air. The tobacco smoke inhaled by the smoker automatically undergoes a reduction in density and is cooled by the air.

According to the present invention, I provide in or for a smoking article, such as a cigarette holder, cigar holder or tobacco pipe, a mouthpiece having within it a smoke tube surrounded by an annular space, this space being connected to the atmosphere by an aperture which is provided in the outer wall of the mouthpiece near the end adjacent the tobacco holder, so that air from the outside atmosphere is drawn into the space and is led to the bit end of the mouthpiece, thereby permitting tobacco smoke and free air to be drawn simultaneously through the mouthpiece.

Embodiments of the invention will now be described by way of example with reference to the accompanying drawings, in which:

Fig. 1 is a plan view of a cigarette or cigar holder with a mouthpiece according to the invention;

Fig. 2 is a longitudinal section with parts in elevation of the invention as shown in Fig. 1;

Fig. 3 is an end elevation of the invention as shown in Fig. l on an enlarged scale;

Fig. 4 is a plan view of a tobacco smoking pipe with a mouthpiece according to the invention; 1

Fig. 5 is a longitudinal section with parts in elevation of the invention as shown in Fig. 4;

Fig. 6 is a longitudinal elevational view partially in section of a detail of the invention;

Fig. 7 is an end elevation of the detail shown in Fig. 6;

Fig. 8 is a longitudinal sectional view of a modification of the mouthpiece in which longitudinal tubes are disposed about the periphery of the inner tube; and

Fig. 9 is an end view showing the tubes of Fig. 8 at the bit end of the mouthpiece.

Referring to the drawings, Figs. 1-3 show a mouthpiece 4 for a cigarette or cigar holder, the holder comprising a tubular stem 7 with a smoke passage 12 therethrough leading from a cigarette or cigar holding socket 13. The mouthpiece 4 has a bore 11 which is internally 2,737,187 Patented Mar. 6, 1956 conically flared with the smaller dimension located near the bit of the mouthpiece and the larger dimension adjacent the tubular stem 7, the larger dimension of the bore being internally threaded for engaging a male threaded connection6 at the end of the tubular stem 7. Integral with the male threaded connection 6 there is provided an inner smoke tube 3, the length of which is just sufficient to extend to the bit end of the bored mouthpiece 4. The threaded engagement of the tubular stem 7 and mouthpiece 4 places the projecting inner smoke tube in spaced relation to the wall of the mouthpiece 4 which defines the conical bore 11, and there is thereby defined an annular space 2 surrounding the inner smoke tube 3. .Aperture 5 in the mouthpiece 4 is positioned adjacent the threaded portion of the bore 11 and permits atmospheric air to be drawn into the annular space 2 and serves to cool the smoke drawn through the inner smoke tube 3 of the mouthpiece, this tube being in unobstructed alignment with the passage 12 in stem 7.

At the bit end of the mouthpiece between the inner surface of bore 11 and the axis of smoke tube 3 are provided longitudinal air passageways 1 defined by radially outwardly projecting splines 14 on the outer surface of inner smoke tube 3 and the inner surface of the bore 11. The air passageways may be inclined to the axis of the tube 3 by including the splines 14, as shown in Fig. 2 and in detail in Fig.6. 7

In Figs. 4 and 5 is shown a tobacco smoking pipe having a bowl 13' with a tubular stem portion 7 with a smoke passage 12 therethrough. On the end of stem portion 7' is a male threaded connection 6' which corresponds to the male threaded connection 6 of Figs. 1-3. A monthpiece 4' for the pipe has a bore 11 which is internally conically flared with the smaller dimension located near the bit end of the mouthpiece and the larger dimension of the bore being internally threaded and engaging the male threaded connection 6'. Integral with the male threaded connection 6' there is provided an inner smoke tube 3', the length of which is just sufficient to extend to the bit end of the bored mouthpiece 4. The threaded engagement of the tubular stem 7' and mouthpiece 4' places the projecting inner smoke tube in spaced relation to the wall of the mouthpiece 4' which defines the conical bore 11', and there is thereby defined an annular space 2' surrounding the inner smoke tube 3'. Aperture 5' in the mouthpiece 4' is positioned adjacent the threaded portion of the bore 11 and permits atmospheric air to be drawn into the annular space 2' and serves to cool the smoke drawn through the inner smoke tube 3' of the mouthpiece this tube being in unobstructed alignment with the passage 12' in the stem 7.

At the bit end of the mouthpiece between the inner surface of bore 11' and the axis of smoke tube 3 are provided longitudinal air passageways 1' defined by radially outwardly projecting splines 14 on the outer surface of inner smoke tube 3 and the inner surface of the bore 11'. The air passageways may be inclined to the axis of the tube 3' by inclining the splines 14' as shown in Fig. 5, and in the detail in Fig. 6.

Figs. 6 and 7 show in greater detail the integral construction of the inner smoke tube and the tubular stem. The male threaded connection 6" on the tubular stem 7" serves to engage the internally threaded dimension at the large end of the bore in the mouthpiece. The smoke passageway 12" extending through the threaded connection serves to bring the smoke into the inner smoke tube 3". The inclination of the splines 14" and passageways 1" is clearly shown.

In Figs. 8 and 9 there is shown a modification of the invention in which the mouthpiece 41 has an inner bore 42 which is cylindrical. The portion immediately adjacent the internally threaded end of the bore 42 is of a larger dimension than the remainder of the bore. An inner smoke tube 31-is-provided Within the bore 42---andhas -a male threaded connection 62-engageable with the internally threaded end of bore 42. At the bit end thereof between the-innersurfa'ce of bore 42 and theaxis of smoke tuhe 3'1-is positioned 'a radially outwardly 'projectin g array of air'-"pass'agewaysiir the form of longitudinally extendin' g tubes8. The'etilarg'edpo'rtion ofth'e bore -i2 providesa substantially cylindrical annularspace 21= into which space an aperture 51 opens thr'ough the mouthpiece 41 to admit cool air.

The 'partic'ular'embodiments which are illustrated in the in View ofthe simple threadedconnection of the mouthpiece with the threadedst'e'm; the smoking article is readily disassembled for cleaning.

It'is thought that th'e inventiona'nd its advantages will be und'crstood fromthe foregoing description and it is apparent that various changesm'ay be made in the form, construction and arrangement of the "parts i without departing from the-"spirit and-scopeoftheinventiononsacrificing its material advantages, the forms hereinbefore described and illustrated in the drawings being merely-preferred-embodiments thereof.
